Network security processing method and system for selecting one of software and hardware cryptographic modules by means of multimedia session information

A system for selecting one of software and hardware cryptographic modules by means of multimedia session information, comprising:

• an information analyzer configured to perform signaling processing of a multimedia session so as to obtain multimedia session information therein, the multimedia session information including a media type and a codec type;
• a network security processor configured to perform network security processing, said network security processor including a key authenticator configured to conduct a key authentication negotiation on the multimedia session, and a cryptographic processor containing said hardware cryptographic module and said software cryptographic module;
• and
• a software/hardware determiner configured to determine which one of said hardware cryptographic module and said software cryptographic module is to perform said network security processing based on the multimedia session information, said software/hardware determiner including a cryptographic module determiner configured to select the use of said hardware cryptographic module or said software cryptographic module, and a cryptographic module determination database connected to said cryptographic module determiner,
• wherein the cryptographic module determination database stores at least one of the media type and the codec type in association with one of the use of said hardware cryptographic module and the use of said software cryptographic module,
• wherein the software/hardware determiner searches the cryptographic module determination database to determine one of the use of said hardware cryptographic module and the use of said software cryptographic module according to at least one of the media type and the codec type obtained by said information analyzer.
